Ammonia

Ammonia Characteristics
• Ammonia is sensitive to pressure and
temperature
– A small volume of liquid anhydrous
ammonia will produce a large volume of
gas at atmospheric pressure.
• Ammonia has a limited flammability range
– 15-28% in air generally found only in
confined space.
– Mixtures of oil and ammonia may reduce
lower level to 8%
• Ammonia has a very strong affinity for
water.
– 1 gallon of water will absorb 1,300 gallons
of ammonia vapor by volume.
